I can tell you about every single bike trail, but almost every road except a few major ones are deadends. That Forest Service has never repaired any non-major road or bridge thats been washed out. This is how they're gonna close off the forest to only hiker use. It's a shame because the vistas you get to on a bike(that once had roads to) are second to none!
Now off my high horse. Check out the bike trail maps on the FS web site, they show alot of the roads that deadend, but still take you out to some neat areas. Go south out of Randle on FR 25 then veer left onto FR 23. 5 or so miles later, take a right onto FR 76 to Tower rock. You can go check out the Cispus center, NF campground, or into the little town. If not and you want dirt, after you cross the bridge, go straight on the dirt road instead of veering right on the pavement to hit either FR 28 which goes to the main St. Helens road FR 25, or FR 28 to FR2810 or FR 29 that both eventually deadends, but take you way up into the Dark Divide. If you don't take FR 76 but keep going straight on FR 23, keep going and just before North Fork campground(CG), take a left onto FR 22, keep going and veer left where the pavement ends. At the next fork with a bridge, veer right onto 2206. Watch carefully for breaks in the trees as there's cool waterfalls along the road. After a few miles, there's Wobbly lake(#273) 2 mile hiking trail to the lake you can swim in. I think if you press on you'll run into FR 21, take a right to Adams fork campground. If not, backtrack to the pavement and take a left onto FR 78 which'll take you to FR 21 too, take a right to Adams fork campground. Take a left to the CG but pass by it, cross the bridge and take the immediate right onto FR 5601 to Takhlakh lake. You'll be on a very ****ty Jeep road, but once at the CG, you'll see why this is an awesome lake to swim at. Be advised that along every route I mentioned, you;ll probably be stopping alot for the views, jumping into falls, swimming holes, cheching out camping areas or CGs, caves, animals, etc.
